Abstract

L'invention concerne un procédé mis en oeuvre dans un réseau de communication sans fil (300) comprenant une pluralité de dispositifs (100), pour rechercher un chemin servant à transmettre des données, d'un dispositif source (110A) vers un dispositif de destination (110D), par l'intermédiaire d'un relais à sauts multiples. Le procédé selon l'invention comprend l'étape qui consiste à émettre, par le dispositif source (110A), une demande de recherche de chemin servant à transmettre des données au dispositif de destination (110D). La demande de recherche de chemin comprend : un premier champ indiquant une limite de comptage de saut, un deuxième champ indiquant un nombre de créneaux (X) nécessaires à la transmission desdites données, un troisième champ indiquant une ID pour le dispositif source (110A), et un quatrième champ indiquant une ID pour le dispositif de destination (110D). Le dispositif source (110A) reçoit alors une réponse de recherche de chemin qui indique un chemin reliant le dispositif source (110A) au dispositif de destination (110D). La réponse de recherche de chemin comprend un premier champ indiquant un nombre de sauts entre le dispositif source (110A) et le dispositif de destination (110D).
